결과적으로 시판 피마자박을 성장하는 병아리 혹은 기타 단위 동물의 단백질 사료로서 이용하기위해서는 다시 제독처리해야함을 알 수 있다. 제독처리 방법 중에서도 끓는 물로 여과하여 독소를 축출하는 방법이 가장 좋고 이 방법이 독소를 전부는 아닐지라도 대부분 제거시키는 방법이다. 피마자박의 아미노산조성을 볼때 그 생물가가 낮은 주요 원인이 라이신 트립토판 그리고 S 함유 아미노산이 부족하기 때문임을 알 수 있다. 제독처리한 피마자박의 라이신과 메치오닌 그리고 트립토판을 첨가하면 대두단백+메치오닌(0.2$\%$) 만큼 병아리성장에 유효함을 알 수 있다. 다른 필수 아미노산의 첨가는 별 효과가 없고 어분 대두단백 혹은 난백의 첨가도 부족한 아미노산을 첨가해 주는 것만큼 효과적이 아니었다. 라이신이 가장 먼저 부족되는 것이고 다음 트립토판이다. 메치오닌은 NRC 권장량의 60$\%$ 밖에 안되나 실제로 피마자박에 적절히 함유한다. 이것은 NRC 권장량이 너무 높다는 스콧트와 그의 동료의 주장과 일치하고 있다. 체중변화를 볼 때 흥미있는 것은 피마자박에 어분을 첨가하면 각 그룹간 병아리 체중의 차이가 심한데 어분대신 아미노산을 첨가하면 그 차이가 현저히 감소한다. (25$\%$와 15$\%$) 이러한 현상은 아미노산이 부족한 사료를 먹으면 성장에 필요한 아미노산 요구량이 개체별로 차이가 있기 때문일 것이다. 피마자박에 아미노산을 첨가하면 단백질 최종이용율이 현저히 증가하나, 이정도는 대두단백+메치오닌(0.2$\%$)에 비하면 이용율이 낮은데 그 이유는 아마 피마자박중의 리그닌과 조섬유 함량이 높기 때문일 것이다. 피마자박의 사료는(사료중 40$\%$) 조섬유가 약 15$\%$나 되어 이것 때문에 사료 섭취량이 대두단백사료 보다 증가하게 되고 사료섭취량이 많으면 단백질 섭취도 많게 되어 피마자박의 단백질 이용율이 낮게 된다. 즉 최종 단백질 이용율은 단백질 섭취량과 역비례한다. 만약 피마자박의 조섬유를 일부 혹은 전부 제거하기만 한다면 양계및 기타 단위 동물의 단백질 사료 자원으로서 그 가치가 훨씬 높아질 것이다. 더욱 희망적인 것은 피마자박 생산자측에 의하면 피마자씨 껍질의 상당한 부분을 제거하는 것은 가능하다고 한다.

A study was conducted to investigate the effect of supplementing earthworm meal on the growth performance and nutrient digestibility of feed in broiler chicks. A total of 120 broiler chicks at 7 days of age were fed the experimental diets containing 0％(Control), 0.2％ and 0.4％ of earthworm meal for 6 weeks. When fed on both starter and finisher diets, the body weight gain and amount of feed intake were significantly higher (P<0.05) in the chicks fed 0.4％ of earthworm meal than those fed 0％ and 0.2％ of earthworm meal. There were no significantly differences in feed. conversion ratio and mortality among the treatments. When fed on both starter and finisher diets, digestibility of dry matter of feed was not affected by the dietary treatment, but crude fat and crude ash digestibilities of feed were tend to increased in chicks fed earthworm meal Digestibility of crude protein of feed in chicks fed 0.4％ of earthworm meal was significantly(P<0.05) improved as compared with those in 0.2％ or control group. These results indicated that the dietary supplementations of 0.4％ earthworm meal were effective in improve digestibility of crude protein of diet resulted improved broiler performance if.. broiler chicks.

This study was conducted to investigate the utilization of defatted soybean meal as a substitute for fish meal in the diet for juvenile flounder (Paralichthys olivaceus). Duplicate groups of average weighing 35 g were fed one of four isonitrogenous ($54{\%}$) and isocaloric (575 kcal/100 g diet) diets containing $0{\%}, 10{\%}, 20{\%} and 30{\%}$ soybean meal for 45 days. Survival rates of all groups were $100{\%}$, Weight gain of fish decreased with increasing dietary soybean meal levels, However, this value was not significantly different between fish fed the control and $10{\%}$ soybean meal diet (P > 0.05). Feed efficiency and protein efficiency ratio decreased with increasing dietary soybean meal levels, but no significant differences were found among fish fed the control, $10{\%}\;and\;20{\%}$ soybean meal diets (P > 0.05). Daily feed and protein intake increased with increasing dietary soybean meal level. Crude protein and moisture content of liver tended to decrease and crude lipid content tended to increase with decreasing of dietary soybean meal levels. Plasma total cholesterol levels of fish fed the diets containing $20{\%}\;and\;30{\%}$ soybean meal were significantly lower than that of fish fed control diet (P < 0.05), Plasma GOT level significantly increased with increasing dietary soybean meal level (P < 0.05). It is concluded that soybean meal can be used as a partial substitute for fish meal up to $10{\%}$ in this dietary formulation for growth of juvenile flounder.

When fed on one of the six isonitrogenous (45%) and isolipic (8%) feed containing 5 or 10% Undaria, 2% wasabi leaf, 2% wasabi stem and 0.5% herb (Obosan) for a period of 8 weeks, 95-98% juvenile flounder survived. Growth, feed efficiency and condition factor of the flounder fed on diet containing 0.5% herb were significantly (p<0.05) higher than those fed on diet supplemented with 10% Undaria. There was no significant (p>0.05) differences in moisture, crude protein, lipid and ash of the flounder receiving the different diets. The flounder fed on diet supplemented with 10% Undaria had the highest moisture but the lowest lipid in liver. Hematological parameters such as red blood cell, hematocrit and hemoglobin and serum constituents such as glucose, total cholesterol and glutamic-oxaloacetic transaminase of the flounder fed on the diets varied but no specific trend became apparent. Lysozyme activity in the serum of the flounder fed on diet supplemented with 5% Undaria and the herb, as well as nitroblue tetrazolium (NBT) reduction of macrophage in the head kidney of the flounder fed on diet containing the herb and 2% wasabi stem were significantly (p<0.05) higher than those receiving control diet. Briefly, the herb supplementation promoted growth and that of Undaria and wasabi stem enhanced non-specific immune response.

Three feeding experiments were carried out to evaluate the effects of fatty acids or lipid sources in diets on the survival, growth and body composition of junenile abalone(Haliotis discus hannai). Diets used in this study contained casein or fish meal as a protein source. Three replicate groups of abalone averaging 160 mg were fed with casein diets containing 12:0, 18:1, 18:2n-6, 18:3n-3, n-3HUFA, squid liver oil (SO), corn oil (CO), beef tallow (BT), SO+CO, and SO+BT, or fed fish meal diets containing SO, CO, BT, SO+CO, SO+BT and not supplemental oil for 20 weeks, respectively. Survival rate, weight gain and soft body weight of abalone were not significantly affected by different fatty acids in the casein diets (P>0.05). Weight gain, soft body weight and shell length of abalone fed the casein diets containing SO, SO+CO or SO+BT were significantly higher (P<0.05) than those of abalone fed the casein diets containing CO or BT. Survival rate of abalone fed the fish meal diets was not influenced by different lipid sources (P>0.05). Weight gain and soft body weight of abalone fed the fish meal diets containing beef tallow (BT or SO+BT diet) were lower than those of abalone fed the diet not added oil or diets containing SO, CO and/or SO+CO(P<0.05). These data indicated that SO or SO+CO was good dietary lipid source for juvenile abalone, and that these oil supplement in diet was not necessary when fish meal was used as a protein source.

A 20-week growth trial was conducted in flow-through aquarum system to investigate the practical dietary carbohydrate sources for juvenile abalone (Haliotis discus hannai). Four replicate grops of the abalone averaging 0.125g were fed one of eight diets containing 24.2% wheat flour (WF), 20% dextrin (DEX), 20% sucorse (SUC), 10% $^{\alpha}$-potato starch+10% $^{\beta}$-potato starch (ab-S), 15% $^{\alpha}$-potato starch (a-S15), 20% $^{\alpha}$-potato starch (a-S20), 25% $^{\alpha}$-potato starch (a-S25), or mixture (MIX) with practical ingredients such as soybean meal, corn gluten meal, cotton seed meal and heat flour. In addition, these formulated diets were compare with macroalgae such as dried sea mustard Undaria (D-SM) or dried sea tangle Laminaria(D-ST). Survival rate, weight gain, shell growth and soft body weight of abalone were not significantly affected by the different dietary carbohydrate sources (P>0.05), whereas those fed a-S15 diet were slightly low. These values of abalone fed D-ST were lowest (P<0.05), followed by those fed D-SM. Lipid contents of soft body from abalones fed a-S25, D-ST or D-SM were significantly lower than those of abalone fed other diets (P<0.05). These data indicate that abalone can equally utilize any carbohydrate sources used in this study.
